Abstract

Presently, in the new HEP experiments we are observing a growing complexity in the interfaces of the analysis tools. As a consequence, end users have to master programming, understand complex frameworks and data storage details before achieving the physics goals. This reduces significantly the efficiency of the analysis process. In order to tackle this problem we propose introducing a new abstraction layer between the end users and the current interfaces. We go further in our approach by proposing to perform the mass event selection by the usage of a visual language that expresses the physics analysis queries in a declarative way. Through our solution we can express complex decay queries easily with no programming efforts, abstracting the storage and optimization details, and reducing the need to deal with the normal framework intricacies. We describe the methodology used designing and implementing the new abstraction layers.
